Many years ago, after the end of a bloody world war, mankind took shelter in six city-states that were peaceful and perfect... at least on the surface. However, Shion—an elite resident of the city-state No. 6—gained a new perspective on the world he lives in, thanks to a chance encounter with a mysterious boy, Nezumi. Nezumi turned out to be just one of many who lived in the desolate wasteland beyond the walls of the supposed utopia. But despite knowing that the other boy was a fugitive, Shion decided to take him in for the night and protect him, which resulted in drastic consequences: because of his actions, Shion and his mother lost their status as elites and were relocated elsewhere, and the darker side of the city began to make itself known.

Now, a long time after their life-altering first meeting, Shion and Nezumi are finally brought together once again—the former elite and the boy on the run are about to embark on an adventure that will, in time, reveal the shattering secrets of No. 6.

[Written by MAL Rewrite]


No. 6 condenses but largely remains faithful to the the original nine-part light novel series. Changes were made to tone down the amount of violence in the series, in addition to creating an alternate ending.

No.6 is a captivating anime and I can honestly say that after having just watched it twice through. But then again, everyone has different tastes and this just may not be your cup of tea. Even so, it couldn’t hurt to try a sip, could it?

NOTE: For my sake, I’m writing Nezumi, as Nezumi, and not “Rat” like in the subs, and Shion instead of Sion, like the MAL character page.

Story – 8/10. No.6 is a utopia, there is no poverty, there are no conflicts, there are no problems. You will live happily and peacefully within these safe walls, and you will wear this read more

Wow, that was painful. Please, anyone reading this, don't bother with this anime. Go pick up a translation of the novels or the manga. I've only read brief summaries of the novel, but those summaries were enough to let me know how good of a show this could have been, and just how far BONES had to go out of its way to make the No. 6 anime a complete trainwreck.

The first three episodes of the show were really interesting. Not fantastic, but enough to get me excited. There's a strong sense of mystery pervading the first episode: Why is this kid being pursued? read more

Had so much potential but was wasted. When I saw the first episode I fell in love with the characters and became very interested in the story. I was so glad this wasn't one of those animes where you had to watch up until episode 4 or 5 before something good happens. It started right out with some action and character development.

Watching the next batch of episodes had me hooked because there was so many things going on with Shion and Nezumi, both apart and together, plus the background of No. 6 and how it got the way it is. The horrible acts committed by read more

Seemed to be lacking in reviews, so decided for me to write my own.
Firstly, although only four episodes in, there are some definite Shonen Ai hints. We still have some more episodes to go before it is confirmed, but it is most definitely on the cards. So do not watch if you aren't into that kind of thing. If not, do try this, it makes for interesting character (and comical) interaction and relationship. (Sometimes even married couple like)

Now onto the main story, set in the near future in a Dystopia. (Google is your friend) Which follows Sion and Nezumi(Rat)'s story that investigates the mysteries of read more
